Brunel to use Camcon Single Cylinder IVT in researching future powertrain concepts

Green Car Congress

Both conventional and unconventional event profiles can be achieved. The conventional camshafts are completely eliminated and valve position can be monitored throughout the event using a specialized sensor. Any valve event profile can be achieved and valve position can be monitored throughout the event using a bespoke sensor.

Cummins & Tula demonstrate Diesel Dynamic Skip Fire (dDSF) cylinder deactivation; up to 66% reduction in NOx on CARB LLC #7

Green Car Congress

Like DSF for gasoline engines, dDSF uses individual cylinder deactivation control strategies to meet torque demand at optimal fuel and aftertreatment efficiency. dDSF improves fuel efficiency by firing all events at the most efficient ratio of air to fuel, allowing optimal combustion at all engine output levels.
